Design of an End-Pumped Laser Source for Generation of High-Energy Nanosecond Pulses at 1.6 µm Wavelength

Abstract

A numerical model for simulating a pulsed laser has been implemented. The modelled laser can generate pulses with a duration of a few nanoseconds and a tunable wavelength. The laser consists of a diode-pumped neodymium-LiYF4 laser that is frequency converted in an intracavity optical parametric oscillator with a KTiOAsO4-crystal. This model was then compared to experimental results to test its validity. It was then used to optimize the design of a laser generating pulses with a tunable wavelength around 1.6 µm.
